A looming traffic nightmare on Florence Avenue has been pushed back yet again.

Florence Avenue near the 5 and 605 interchange in northeast Downey will be reduced to one lane in March 2015, according to Caltrans’ latest timeline. The closure comes as Caltrans is expected to begin work on the 5 Freeway in Downey this July. Heavy freeway construction is already well underway in Norwalk.

The closure was originally anticipated to begin immediately following Labor Day 2014, but those plans were pushed back, city officials said.

Caltrans is widening the 5 Freeway from Downey city limits to the Orange County border. In Downey, construction plans include a pedestrian overpass at Cecilia Street, a northbound on-ramp to the 5 Freeway at Florence Avenue, wider freeway shoulders and a carpool lane.
